Calculate : free your mind from math.
Calculate lets you see the whole equation, so you don’t need to keep your position in a long list of figures.
Calculate shows all your previous calculations and lets you paste the result of any calculation into your current equation, so you don’t need to type numbers in over and over.
This version has a new math parser that is more powerful than before. Calculate now has a bunch of new constants, too. In Notification Center, the Calculate widget can now have its expression pasted directly into the app, in case a little bit of math gets more complicated than expected.
Side note: There are more functions than are visible in the formulas bar, so you can type in a name and try it out.
With Family Sharing set up, up to six family members can use this app.
